The 'spidey-sense' is commonly represented as manifesting an “itching” or “tingling” feeling at the base of Spider-man's skull (Lindsay n.d.; “Spider-Man's Powers and Equipment”, Wikipedia).
This ability revolves around a Spider-Man's enhanced brain's ability to intake and response to stimuli at an accelerated rate, acting as a precognitive ability to sense potential or immediate danger.
Thanks to his Spider-Sense, Spider-Man can dodge physical attacks, energy blasts, weaponry, and even explosions. Spider-Man has also been known to use his ability to find hidden objects such as passageways.
Most spiders rely heavily on vibration, smell, touch, and taste instead of vision. Web-spinning spiders rely on tiny vibrations in their silk to signal that prey has contacted the web, or to warn of incoming predators. Webs are a way of expanding the sensory range of a spider.
Spiders, like other arthropods, not only have mechano-sensitive cuticular exteroreceptors (hair-like sensilla or setae) but also proprioreceptors (slit sensilla, kind of embedded biological strain gages in the exoskeleton; hair-like sensilla; internal joint receptors) usually found in increased density near the joints.
A spider's sense of touch is its most well developed sense. The spider's body hair and spines are extremely sensitive to touch and to vibrations. Spiders can feel a puff of air so gentle that it only stirs one hair. Spiders do not have ears, but have very good hearing.
Peter Parker's Spider-Sense is powerful and comes in handy quite often, but the Flash's brain works at such high speeds that he can detect and respond to threats at a moment's notice. Technically, Spidey tends to have a longer window of time to react than the Flash, so his ability could be seen as more useful.
While the theory is unproven, it is likely that spiders can detect human fear. However, there are only few studies about this topic and it is not yet known for certain. Different animals have sensory organs that are able to identify different stimuli.
Daredevil because his hearing can travel pretty far. Stan Lee himself stated that Daredevil's Radar Sense is better than Spider-Man's Spider-Sense. Daredevil can see 150 yards in 360 degrees without concentrating, and even more when he does concentrate.
Iron Man's new immunity to spider-sense may be of use sooner than readers realize. With the recent return of the Superior Spider-Man and the maniacal Chasm on the loose once more, negating their spider-sense would give Tony a big leg up in a scrap.
At one point in Into the Spider-Verse, we see Miles' spidey-senses tingle when he meets his Earth's Peter Parker, but they are purple and green before they shift to blue and red. The Prowler's signature colors are purple and green, so this foreshadows the twist of Prowler-Miles from Earth-42.
One word of caution: It is always best to avoid touching a Spider. While they never actively seek human contact, they will bite if they feel threatened or endangered.
While Peter Parker has been shown dabbling with social drinking in sporadic instances – ordering a beer in one comic and getting drunk on champagne at social gatherings – it's actually become a given that Spider-Man isn't a drinker.
Spiders really don't like strong scents such as citrus, peppermint, tea-tree, lavender, rose or cinnamon. Add 15 to 20 drops of your chosen essential oil or a couple of capfuls of Zoflora fragrance to a spray bottle filled with water, and spritz around the house.
What Smell Attracts Spiders? The stinky smell of sweaty socks might repulse humans, but scientists now find it enthralls mosquitoes and spiders. The odor apparently helps the creatures hunt down their victims — the mosquitoes want to feed on people, while the spiders prefer to devour the mosquitoes.
“These results suggest that P. regius is capable of individual recognition based on long-term social memory,” write the authors. It wouldn't be the first time jumping spiders have exhibited a trait that was previously thought to be associated with sociality.
The fight might be close, but Spider-Man would have a difficult time slowing down the Flash enough to beat him. Spider-Man definitely has a chance to land a few good blows, but the Flash is just too fast and unpredictable for him to beat.
Both have the ultimate counter attacks to each other. Spider-Man is stronger, more durable and has more ways to use his power. Flash is way way way WWWWAAAYYYY FASTER. They both have about the same amount and same kind of hax.
Many other mammals typically see just some shades of blue and green light. Many spiders also have a crude form of color vision, but for them it's usually based on green and ultraviolet hues. This extends their vision into the deep violet end of the spectrum — well beyond what people can see.
Spiders don't have ears like we do, and many have poor eyesight. But they can sense vibrations, like those that happen when an unlucky insect touches their webs. And instead of eardrums, spiders hear using tiny, sensitive hairs that move in response to sounds.
